Description

Technical Field

[0001] This invention relates to the field of power facility technology, specifically to a variable cross-section electric pole. Background Technology

[0002] Currently, most of the poles used in power transmission lines are either constant-diameter poles or tapered poles. Constant-diameter poles have the same cross-sectional dimensions throughout their entire length. Although they are relatively simple to manufacture, their stress performance is not entirely reasonable. According to the stress characteristics of the pole, the bending moment at the root is the largest, while the bending moment at the top is smaller. In order to meet the stress requirements at the root, constant-diameter poles must use a larger diameter throughout the pole, resulting in material waste and increased costs. On the other hand, the cross-sectional diameter of tapered poles gradually decreases from the root to the top, which to some extent conforms to the stress characteristics.

[0003] Chinese patent application number 202021434921.6 discloses a tapered utility pole for convenient cable maintenance, comprising a pole body, a mounting plate fixed to the top of the pole body, insulators symmetrically mounted on both sides of the top of the mounting plate, and a vertical pole connected to the middle of the top of the mounting plate. A baffle is fixed to the top of the vertical pole, and insulating winding rods are symmetrically connected to both ends of the lower surface wall of the baffle. The outer surface wall of the insulating winding rods has winding grooves, and buffer springs are symmetrically connected to the lower end of the outer surface wall of the pole body. However, after the pole body is buried, its overturning resistance mainly depends on the foundation soil. Under conditions of soil settlement or horizontal migration, the pole is prone to tilting or even toppling.

[0004] Furthermore, as the service life increases, the cable support hardware at the top of the pole may loosen due to wear, corrosion, or decreased bolt preload, causing the cable to sway and affecting its stability. Moreover, the lack of real-time monitoring methods for the pole's posture and the condition of the hardware makes it difficult to detect potential pole tilting or loose hardware in a timely manner, posing a risk to the safe operation of the transmission line. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a variable cross-section pole with high stability, convenient maintenance and monitoring and early warning capabilities, which can effectively meet the requirements of safe, stable and long-term use of transmission lines and effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a variable cross-section pole, comprising a pole body, a sealing disc at the top of the pole body, and a support assembly at the top of the pole body; The support assembly includes a first clamp and a second clamp. The first clamp is detachably sleeved on the rod body, and supports are provided on both sides of the first clamp. The side of the rod body is provided with a side groove corresponding to clamp one and clamp two. A groove seat is movably fitted in the side groove, and the groove seat is fixedly connected to the inner wall of clamp one and clamp two. It also includes a sliding rod that passes through the middle of the sealing disc, and a rope is provided at the bottom end of the sliding rod, with a counterweight seat at the bottom end of the rope. It also includes a limiting seat, which is located on the bottom side of the inner wall of the rod. A reinforcing rod slides through the middle of the limiting seat, and a cone seat corresponding to the counterweight seat is provided at the top of the reinforcing rod. Both sides of the slide rod have slidably passing through a limiting rod, and the end of the limiting rod near the inner wall of the rod body is provided with a positioning seat.

[0007] Preferably, the rod body has an overall conical structure, and the interior of the rod body has a conical hollow structure; The support has mounting holes.

[0008] Preferably, the second clamp is detachably sleeved on the rod body and located below the first clamp, and both sides of the second clamp are provided with inclined support rods, the top of the support rods being detachably connected to the support. Both clamp one and clamp two consist of two arc-shaped plates, which are connected by bolts.

[0009] Preferably, the slide bar extends into the interior of the rod body, and the middle part of the sealing disc is provided with an elastic sleeve that is fitted onto the outside of the slide bar.

[0010] Preferably, the bottom end of the reinforcing rod is provided with a cone, and a photoelectric sensor is provided between the end faces of the counterweight and the cone. Both the counterweight and the cone are provided with a power module, a processing module and a wireless communication module.

[0011] Preferably, a side hole is provided at the bottom of the side wall of the rod body, the side holes are arranged in a ring array, an auxiliary rod slides through the inside of the side hole, the inner end of the auxiliary rod is provided with a wedge-shaped block, and the outer end of the auxiliary rod is provided with a sharp part.

[0012] Preferably, it also includes a connecting seat, which is located at the top of the slide rod. Both ends of the connecting seat can be detachably connected to guide rods. The guide rods on both sides pass through the supports on both sides respectively. Threaded cylinders are threaded onto the upper and lower sides of the guide rods. The bottom ends of the guide rods on both sides are provided with a base.

[0013] Preferably, one side of the positioning seat is fully fitted with the inner wall of the rod, the connection surface between the positioning seat and the limiting rod is a vertical plane, and the positioning seat cooperates with the corresponding slot seat.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses a sliding rod to raise and lower, causing the counterweight to reciprocate and strike the cone seat, thereby driving the cone head at the bottom of the reinforcing rod to continuously insert into the soil at the bottom of the foundation pit, achieving central anchoring of the pole body. During the downward feeding of the reinforcing rod, the cone surface of the cone seat cooperates with the inclined surface of the wedge block to squeeze and push the auxiliary rod to slide outward so that its sharp part inserts into the surrounding soil, forming radial anchoring. Together with the central reinforcing rod, it forms a three-dimensional anchoring system, effectively enhancing the overall stability of the pole under complex working conditions such as wind load and cable tension.

[0015] 2. When the clamps of the utility pole become loose due to wear or corrosion after long-term use, the present invention pulls the sliding rod upward to cause the positioning seat to contract along the conical inner wall towards the center, pushing the slot seat to slide towards the center, thereby applying a continuous radial tension force to the clamps, compensating for the fit clearance, restoring the clamping force, avoiding the swaying of the support and the swinging of the cable caused by the loose clamps, and improving the long-term stability of the support assembly.

[0016] 3. This invention, by setting a photoelectric sensor between the end faces of the counterweight and the cone base, and incorporating a power supply module, processing module, and wireless communication module, can monitor the pole's posture in real time. When the pole tilts, a permanent deviation occurs between the counterweight and the cone base, causing the optical signal to be interrupted. After the processing module identifies this, it issues a tilt warning via the wireless communication module. When the support assembly shakes, causing the slide bar to swing, the photoelectric signal will intermittently switch on and off. The processing module can distinguish between tilt and swaying faults based on the signal characteristics, achieving accurate identification and remote warning, facilitating timely handling by maintenance personnel and ensuring the safe operation of the line.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1 Please see Figure 1-4 According to embodiment 6, this embodiment provides a variable cross-section pole, including a pole body 1. The pole body 1 has an overall conical structure, and the inside of the pole body 1 is a conical hollow structure.

[0021] The top of the pole body 1 is provided with a support assembly 2, which includes a first clamp 201 and a second clamp 203. The first clamp 201 is detachably sleeved on the pole body 1. Both sides of the first clamp 201 are provided with supports 202, and the supports 202 are provided with mounting holes.

[0022] Specifically, the pole body 1 is preferably precast from reinforced concrete, the support 202 is used to support the cable, and the mounting hole is used to install and fix the insulator.

[0023] Clamp 203 is detachably sleeved on rod 1 and located below clamp 201. Both sides of clamp 203 are provided with inclined support rods 204. The top of the support rods 204 is detachably connected to the support 202. Clamp 1 201 and clamp 203 are both composed of two arc-shaped plates, which are connected by bolts.

[0024] Specifically, the support rod 204 is used to support the support 202, and the clamp 203 is used to fix the support 202 in an auxiliary manner.

[0025] The top of the rod body 1 is provided with a sealing disc 101, and also includes a slide rod 3. The slide rod 3 passes through the middle of the sealing disc 101 and extends into the interior of the rod body 1. The middle of the sealing disc 101 is provided with an elastic sleeve that is sleeved on the outside of the slide rod 3.

[0026] Specifically, the sealing disc 101 is used to seal the inner top of the sealing rod 1, and the elastic sleeve is used to prevent friction and wear between the sliding rod 3 and the sealing disc 101. The elastic sleeve is preferably made of fluororubber and adopts a lip-shaped dynamic sealing structure, which not only ensures that the sliding rod can slide freely along the axial direction, but also achieves dynamic and static sealing between the sliding rod and the sealing disc, preventing rainwater, moisture and dust from entering the interior of the rod 1.

[0027] It also includes a connecting seat 4, which is located at the top of the slide rod 3. Both ends of the connecting seat 4 can be detachably connected to guide rods 401. The two guide rods 401 pass through the supports 202 on both sides respectively. The upper and lower sides of the guide rods 401 are threaded with threaded cylinders 402. The bottom ends of the two guide rods 401 are jointly provided with a base 403.

[0028] Specifically, by rotating the upper and lower threaded cylinders 402, the two threaded cylinders 402 are respectively pressed against the upper and lower surfaces of the support 202, thereby fixing and limiting the guide rod 401. By rotating the upper and lower threaded cylinders 402 to a position away from the support 202, the position of the guide rod 401 can be moved up and down by the base 403, thereby controlling the slide rod 3 through the connecting seat 4.

[0029] The bottom end of the slide bar 3 is provided with a rope 301, and the bottom end of the rope 301 is provided with a counterweight 302.

[0030] Specifically, the rope 301 is preferably a stainless steel wire rope, with both ends fixed to the bottom of the slide bar 3 and the top surface of the counterweight 302 respectively by pressing and locking buckles, to ensure tensile strength, impact resistance and aging resistance.

[0031] It also includes a limiting seat 303, which is located on the bottom side of the inner wall of the rod body 1. A reinforcing rod 304 slides through the middle of the limiting seat 303. The top of the reinforcing rod 304 is provided with a cone seat 305 corresponding to the counterweight seat 302, and the bottom of the reinforcing rod 304 is provided with a cone head.

[0032] Specifically, in the initial state, the counterweight 302 and the cone 305 are in corresponding and close positions, and the central axis of the rod 1 coincides with that of the counterweight 302 and the cone 305. By controlling the sliding rod 3 to rise and fall, the rope 301 drives the counterweight 302 to rise and fall. The reciprocating rise and fall of the counterweight 302 impacts the cone 305 downwards, and the reinforcing rod 304 can be inserted into the ground through the cone head. This strengthens the fixation of the rod 1 after it is buried in the ground, preventing the rod 1 from tilting or falling.

[0033] A photoelectric sensor is provided between the end faces of the counterweight 302 and the cone 305. Both the counterweight 302 and the cone 305 are equipped with a power module, a processing module and a wireless communication module.

[0034] Specifically, the photoelectric sensor is set at the center between the end faces of the counterweight 302 and the cone 305. The photoelectric sensor is preferably a through-beam photoelectric sensor. Under normal working conditions, the light emitter and receiver of the photoelectric sensor between the counterweight 302 and the cone 305 correspond and receive the light signal normally. When the slide bar 3 shakes or the rod 1 tilts, the photoelectric sensor between the counterweight 302 and the cone 305 will deviate, and a corresponding characteristic signal will be generated. The processing module processes the signal and transmits it to an external terminal through the wireless communication module to remind the staff to perform maintenance.

[0035] The power module is preferably an industrial-grade lithium-ion battery, which meets the outdoor battery life requirement of more than 5 years. The wireless communication module is preferably NB-IoT / LoRa low power wide area technology. The antenna is led out to the outside of the pole body 1 through the sealing disk 101 via a flexible feed line, avoiding the signal shielding of the metal structure and ensuring communication stability.

[0036] Furthermore, after the base of pole 1 is placed in the pit but before it is fixed, the verticality of pole 1 can be detected by whether the photoelectric sensor is receiving signals normally and continuously.

[0037] It should be noted that when the rod 1 tilts, the photoelectric sensor between the counterweight seat 302 and the cone seat 305 will permanently deviate. When the slide rod 3 shakes, the photoelectric sensor on the counterweight seat 302 will swing through the rope 301. At this time, the photoelectric sensor between the counterweight seat 302 and the cone seat 305 will deviate intermittently, thus determining whether the rod 1 tilts or the slide rod 3 shakes.

[0038] A side hole 306 is provided at the bottom of the side wall of the rod body 1. The side holes 306 are arranged in a ring array. An auxiliary rod 307 slides through the inside of the side hole 306. A wedge block 308 is provided at the inner end of the auxiliary rod 307, and a sharp part is provided at the outer end of the auxiliary rod 307.

[0039] Specifically, during the process of the reinforcing rod 304 being fed downward by the impact of the counterweight 302 on the cone seat 305, the cone surface of the cone seat 305 will cooperate with the inclined surface of the wedge block 308 and squeeze the auxiliary rod 307 to move horizontally outward of the rod body 1, so that the sharp part of the auxiliary rod 307 inserts into the soil around the rod body 1, thereby further preventing the rod body 1 from tilting and falling over.

[0040] In use, before the pole 1 is buried in the foundation pit, clamp 1 201 is fixed to the top of the pole 1 at a preset position using two arc plates and bolts. The supports 202 on both sides of clamp 1 201 are used to support the transmission line. The mounting holes on the supports 202 can be used to fix the insulator and cable. Then clamp 203 is fitted and fixed to the position below clamp 1 201 on the pole 1. The two ends of the inclined support rods 204 on both sides are detachably connected to clamp 203 and supports 202 with screws, forming a triangular support structure with the support rods 204, which provides auxiliary support for supports 202.

[0041] In the initial state, the slide rod 3 passes through the elastic sleeve in the middle of the sealing disc 101 and penetrates the top of the rod body 1. The connecting seat 4 at the top of the slide rod 3 is detachably connected to the guide rods 401 on both sides. The guide rod 401 passes through the support 202 and completes the initial limit of the guide rod 401 by tightening the upper and lower sets of threaded cylinders 402.

[0042] After installation, rod 1 is buried in the pit. After rod 1 stands upright in the pit and remains stationary for a certain period of time, the photoelectric sensor is used to check whether rod 1 is in a vertical state. Fine adjustments are made based on the detection results. After rod 1 is detected to be in a vertical state, subsequent installation is carried out. After installation, the counterweight seat 302 and the cone seat 305 are in a corresponding and coaxial position in a stationary state.

[0043] After the rod 1 is buried, rotate the threaded cylinders 402 on both sides to move both sets of threaded cylinders 402 away from the support 202, releasing the restriction on the guide rod 401. The worker holds the base 403 and drives the guide rod 401 to move up and down vertically. The guide rod 401 drives the slide rod 3 to move up and down synchronously through the connecting seat 4. The slide rod 3 pulls the counterweight seat 302 to move up and down in the hollow cavity of the rod 1 through the rope 301. When the counterweight seat 302 moves downward, it will impact the top surface of the cone seat 305. The impact force is transmitted to the reinforcing rod 304 through the cone seat 305, pushing the reinforcing rod 304 to slide down along the guide hole of the limiting seat 303, so that the cone head at the bottom of the reinforcing rod 304 is continuously inserted into the soil at the bottom of the pit, forming a central anchor for the rod 1, improving the overturning resistance of the rod 1, and preventing the rod 1 from tilting and falling due to soil settlement and horizontal migration.

[0044] During the downward feeding of the reinforcing rod 304, the conical outer wall of the cone seat 305 is pressed against the inclined surface of the wedge block 308 arranged in a ring array. As the cone seat 305 continues to feed downward, the horizontal component of the cone surface pushes the wedge block 308 to drive the auxiliary rod 307 to slide along the side hole 306 to the outside of the rod body 1, so that the sharp part of the outer end of the auxiliary rod 307 is inserted into the foundation pit soil around the rod body 1, forming a radial anchoring of the rod body 1, and cooperating with the central reinforcing rod 304 to form a three-dimensional anchoring system, thereby improving the stability of the rod body 1 under complex loads such as wind load and cable tension.

[0045] It should be noted that during the process of the counterweight 302 hammering the cone seat 305 downwards, in order to reduce the impact of vibration on the electrical components inside the counterweight 302 and the cone seat 305, a buffer pad, such as a rubber buffer pad, can be set between the counterweight 302 and the cone seat 305. The electrical components are installed through a vibration damping structure to avoid damage from the hammering vibration.

[0046] After the foundation pit reinforcement is completed, rotate the threaded cylinders 402 on the upper and lower sides of the guide rod 401 so that the two sets of threaded cylinders 402 abut against the upper and lower surfaces of the support 202 respectively, thus locking the guide rod 401 and the slide rod 3 in position.

[0047] During normal use of the pole 1, the photoelectric sensor installed between the counterweight 302 and the cone 305, together with the built-in power module, processing module and wireless communication module, realizes real-time monitoring and abnormal warning of the pole 1's attitude. Under normal working conditions, the counterweight 302 and the cone 305 keep axially aligned, the light emitter and light receiver of the through-beam photoelectric sensor are precisely aligned, the light receiver can continuously and stably receive light signals, and the processing module determines that the pole 1 is in a normal attitude.

[0048] When rod 1 tilts, rod 1 causes cone seat 305 to shift at the same angle. Meanwhile, counterweight seat 302 is suspended from the bottom of sliding rod 3 by rope 301 and remains vertical under the action of gravity. At this time, a permanent deviation occurs between counterweight seat 302 and cone seat 305, and the light signal reception of photoelectric sensor is interrupted. After the interruption time exceeds 1 minute, an abnormal signal is generated. After the processing module collects the continuous abnormal signal, it transmits the tilt warning signal to the remote terminal device through the wireless communication module to remind maintenance personnel to carry out timely inspection and maintenance.

[0049] When the support assembly 2 shakes abnormally, it will cause the slide bar 3 to shake. The shaking of the slide bar 3 is transmitted to the counterweight 302 through the rope 301, causing the counterweight 302 to swing. At this time, the light signal of the photoelectric sensor will intermittently switch on and off. The processing module can distinguish between the tilting fault of the rod 1 and the shaking fault of the support assembly 2 based on the characteristics of the signal, and upload the corresponding abnormal signal to the equipment terminal to achieve accurate identification and early warning of different fault types, and ensure the safe operation of the power transmission line.

[0050] Therefore, the monitoring and early warning system can simultaneously identify tilt and loosening faults. For loosening faults, gap compensation can be completed directly by controlling slide bar 3. Monitoring, early warning and rapid repair can be achieved without replacing clamps and removing cables, reducing maintenance difficulty and safety risks.

[0051] Example 2 However, with prolonged use, the wear and corrosion of clamps 201 and 203 increased, leading to a decrease in the fixing effect on support 202. This caused the cable to sway under wind, causing support 202 to shake and affecting the safety of power transmission. Therefore, the following improvements were made: Please see Figure 5 The side of the rod body 1 is provided with a side groove 205 corresponding to the first clamp 201 and the second clamp 203. A groove seat 206 is movably fitted in the side groove 205. The groove seat 206 is fixedly connected to the inner wall of the first clamp 201 and the second clamp 203.

[0052] Both sides of the slide rod 3 slide through the limiting rod 404. The end of the limiting rod 404 near the inner wall of the rod body 1 is provided with a positioning seat 405. One side of the positioning seat 405 is fully in contact with the inner wall of the rod body 1. The connection surface between the positioning seat 405 and the limiting rod 404 is a vertical plane. The positioning seat 405 cooperates with the corresponding slot seat 206.

[0053] Specifically, the contact surface of the positioning seat 405 is a conical arc surface that fits the inner wall of the rod 1. By controlling the slide rod 3 to move upward, the positioning seat 405 moves upward. Since the inside of the rod 1 has a conical structure and the diameter gradually decreases from bottom to top, the positioning seats 405 on both sides of the slide rod 3 move in opposite directions. When the top of the positioning seat 405 passes through the slot seat 206, the vertical side of the positioning seat 405 gradually abuts against the inner wall of the slot seat 206. As the positioning seat 405 continues to move upward, the slot seat 206 is continuously subjected to a force in the direction of the slide rod 3, thereby fixing the clamp 1 201 and clamp 2 203, preventing the clamp 1 201 and clamp 2 203 from loosening due to wear or corrosion after long-term use, and avoiding the shaking of the support 202 and the cable.

[0054] During use, during the installation of clamp 1 201 and clamp 203, the slot seat 206 is inserted into the corresponding side slot 205. The slot seat 206 can reciprocate within the side slot 205 along the radial direction of the rod 1. After the rod 1 is installed, the slide rod 3 is locked by tightening the upper and lower threaded cylinders 402 in opposite directions. At this time, the positioning seat 405 is located below the slot seat 206, and the limiting rod 404 can slide freely radially along the sliding through hole of the slide rod 3. Under the limiting action of its own weight and the inner wall of the rod 1, the fitting arc surface of the positioning seat 405 remains in contact with the inner wall of the rod 1, and no radial force is applied to the slot seat 206, which does not affect the normal installation and initial fixation of clamp 1 201 and clamp 203.

[0055] When the rod 1 has been used for a long time, the wall thickness of clamp 1 201 and clamp 203 may be reduced due to environmental corrosion and wear, or the bolt preload may be weakened due to long-term wind load vibration, resulting in a gap between the clamp and the rod 1. When the clamping force decreases and the support assembly 2 becomes loose, the counterweight seat 302 will swing through the slide rod 3. At this time, the photoelectric sensor will generate an intermittent photoelectric signal, actively judging that the support assembly 2 is loose and notifying the maintenance personnel. The maintenance personnel will rotate the threaded cylinders 402 on the upper and lower sides of the guide rod 401 to make both sets of threaded cylinders 402 disengage from the abutment state with the support 202, release the lock between the guide rod 401 and the slide rod 3, and drive the guide rod 401 to move upward in the vertical direction through the base 403. The guide rod 401 drives the slide rod 3 to slide upward synchronously through the connecting seat 4. During the upward sliding of the slide rod 3, the limit rod 404 and the positioning seat 405 move upward along the rod 1.

[0056] Because the hollow inner cavity of rod 1 is a conical structure with an inner diameter that gradually decreases from bottom to top, as the positioning seat 405 moves upward, the conical inner wall of rod 1 exerts continuous radial pressure on the positioning seat 405, pushing the positioning seats 405 on both sides to move in opposite directions along the guide of the limiting rod 404 towards the central axis of the slide rod 3. When the top of the positioning seat 405 passes through the slot seat 206, the vertical side of the positioning seat 405 is completely in contact with the inner end face of the slot seat 206. As the slide rod 3 continues to pull upward, the positioning seat 405 continues to contract towards the central axis of rod 1, continuously applying a force towards the center of the slide rod 3 to the slot seat 206, and causing the slot seat 206 to slide towards the center of the slide rod 3. The outer end face of the slot seat 206 simultaneously applies a continuous radial tension force to the inner side walls of clamp 1 201 and clamp 2 203, compensating for the fit clearance caused by wear and corrosion of the clamp, and restoring and improving the clamping force between the clamp and rod 1.

[0057] At this time, the same sliding rod 3 is not only the impact driving component for anchoring construction, but also the driving component for anti-loosening of the clamp, and the signal transmission component for loosening of the support assembly 2.

[0058] After completing the anti-loosening and locking operation of the clamps, rotate the threaded cylinders 402 on both sides of the guide rod 401 again, so that the two sets of threaded cylinders 402 press against the upper and lower surfaces of the support 202 respectively, and complete the locking of the guide rod 401 and the slide rod 3 again. After the slide rod 3 is locked, the position of the positioning seat 405 is simultaneously fixed, thereby forming a continuous and stable radial limit on the slot seat 206, so that the clamp one 201 and clamp two 203 are always in a taut state, preventing the clamps from loosening during the long-term use of the pole body 1, preventing the support 202 from shaking and the cable from swinging due to the clamps loosening, improving the long-term stability of the top support assembly 2, and ensuring the safe operation of the transmission line.

[0059] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
